OLD BT Wiring

[amish99]

Hi guys,

im stuck in a pickel at the moment, trying to redo the house but hit a road block in term of the telephone sockets,

I was going about replacing all the old socket with new chrome ones when i noticed every socket on the lower ground floor were all containing capaciters, therefore i assume they are master sockets, i traced all the wires down and they all leed to the junction box, and the wiring is pretty old as the 4 colours are brown, blue green orange,

am i allowed to replace these with news 1 or not? i also want to add an extra socket and run it from one of these sockets,

cheers

Maybe post for help on the alarms and telephone forum someone there might know I thought domestics only had one master socket

Forgetting part P as far as BT are concerned you can add your own sockets etc but you have to take the face plate of the master socket, as far as I am aware you have to get BT to change the master socket (we got this done free of charge) then you can freely add to it providing you follow the wiring guidlines and consider REN etc.

Someone have 'friged' the BT wiring.

The correct method should be:
Cable on to site- terminate on master socket- then a cable to the next socket (secondary) and then from the 1st 2ndry to the next position and on and on.

I'd change the old cables and rerun:-

a) because existing stuff is wrong
b) broadband would like all those capicitors, and resistors (if master has lighting protection and supression circuits)
c) Broadband prefers CW1308 twisted pair cables.

Master sockets make no difference at all to a BB connection(providing you have BB?)-all(SIN compliant) microfilters have capacitors in as part of BT's SIN specification.

From a BB perspective the best wiring method is :- NTE5 master socket at point of cable entry, fit a 6 way ADSL filter to this, run a dedicated extension to your modem/router(unless you can site it at the master socket), then run filtered extensions off the master socket filter.
